Modular IR filter array
Absorptive Eccosorb filter blocks mounted directly at the 20 millikelvin mixing chamber plate, suppressing thermal infrared photons to prevent quasi-particle generation in sensitive Josephson junctions.
Thermally anchored attenuators
Gold-plated oxygen-free copper heat sinks clamping precision RF attenuators across 4 Kelvin, 700 millikelvin, and 10 millikelvin stages to balance thermal dissipation against fridge cooling capacity.
128-channel coaxial loom
Semi-rigid beryllium-copper and superconducting niobium-titanium lines calibrated for matched group delay, delivering sub-60 dB inter-channel isolation across DC to 8 GHz control envelopes.
